Con and conne also exist in Québec and are frequently used, but they weren’t adopted until the second half of the 20th century, influenced by French films. This slang term was not used in Québec before the Second World War.

On that Wikipedia page, con and conne were given as synonyms of épais and épaisse, which are frequently used in Québec in the sense of “idiot.”

What about colice?

We’ve seen this before on OffQc but more often spelled on the blog as câlice and câlisse. In colice de conne, the colice de part means “fucking.”
